Application filed Serial No. 819,453.

To all whom it may concern Be it known that I, FRANoIs JOHN Wrrrs,

a subject of His Majesty the King of Eng a guard for nose glasses, having projections divided by a depression, the walls ofwhich taper toward each other and in direction of the nose, the depression receiving and gripping the flesh to hold the glasses in position.

The invention also coniprehends improve ments in the details of construction and arrangement of parts which will be hereinafter described and particularly pointed out in the claims.

Fig. 1 represents a strip of metal cut to the desired shape and size, suitablefor making a pince-nez of average size; Fig. 2 is an enlarged cross section of the plaquet, the nose of the wearer being shown in dotted lines; Fig. 3 shows the pince-nez viewed from above, with the spring opened ready for fixing in position on the nose. The butterfly wing action is indicated by the inclination of the lenses 9 and g to the plane of rest shown by the dotted line m m. Fig. 4: is an enlarged view of the plaquet a, and may represent the bare metal, finished suitably smooth for contact with the skin, or it may represent the metal work of the plaquet insulated with cork, celluloid, tortoise shell or other suitable material as individual cases may require.

In carrying out the present invention the metal work forming the bridge of the pinceneZ, i. athat between (land cl Fig. 1 and the broadened strip at both extremities a anda is rendered flexible by rolling or hammermg. pressed or cut into surface of the plaquets a and a running throughout the length of the plaquet, and so shaped as to form a stop Z and Z Fig. 4 with a rounded gripping edge I disappears.

An acute angled groove 0 is im-' or surface Z, rising to a plane slightly higher than that of the first similarly rounded gripping edge or. surface 70. The object of the edges and groove is that when placed in position on the nose, the flesh of the nose shall lightly embed itself before the edges and into the grooves and thereby act as a preventive to the falling off of the pince-nez.

The small tabs 6 andli are drilled and suitably tapped to take the screws fand f. The shaping and bending is next proceeded with; the bridge or spring y being curved outward and possibly slightly upward as a particular nose may require; at (Z and d the metal is doubled back beneath, forming a complete return as far as h and h Fig. 3, where it is then bent downward at about right angles. The bending at d and d is hammered, keeping the metal at that spot as far as possible in a vertical plane, and by this means the flexibility of the bridge piece is extended gradually onward to the bends h and it where to all practical purposes it Fromd and d onward to h and h the metal work gradually broadens and stilfens. At 0 and 0 the four drilled tabs are bent parallel to one another, and to the plane in which the lenses are-to be mounted, and thus are made to form the clamps for the lenses, while the strips 6 and e" are curved into close contact with the edges of the lenses, giving rigidity to the fixture of the lenses in their clamps.

At p and pan abrupt return of the metal work upward forms the plaquets, the exact tilt and adjustment of which can be arranged to suit as a case may need.

What I claim as my invention and desire to secure by Letters Patent of the United plurality of members, each member c0mpris specification in the presence of tWo subscribing a plurality of gripping faces divided by ing Witnesses. a, central depression, one of said gripping FRANCIS JOHN WITTS. faces being higher than the other of said Witnesses: 5 faces. IVOR LLEWELLYN Wl'rTs In testimony whereof I have signed this FRANK BLAKEY.
